To'aZZ whom it may concern Be it known that l[, FRANK J. WAGNER, acitizen of the United States, and resident of Cleveland in the county ofCuyahoga and State of Uhio, have invented certain new and usefulImprovements in Collecting- Bags for Vacuum'Cleaners, of which I herebydeclare the following to be a full, clear, and exact description, suchas will enable others skilled in the art to which it appertains to makeand use the same.

The objects of the invention are to pro vide an improved form ofconstruction for the bag or receptacle of avacuum sweeper or cleaner,whereby increased practicability and efliciency in the use thereof isobtained.

l-Ieretofore the bag which receives the dust from the outlet tube of themachine has been arranged in an inclined position and provided with alarge opening at the upper end through which the dust can be dischargedafter it has been filled, the inlet opening being small and located atthe lower end of the bag.

This form of construction isdisadva-ntageous in that the bag must beremoved from the machine and turned upside down to re movethe dust. Thepresent invention is designed to overcome this difficulty and alsopresents features preventing the dust from returning into the machinewhen fluctuations in pressure occur.

The invention further. comprises the combination and arrangement ofparts and construction of details hereinafter described, shown in theaccompanying drawings and specifically pointed out in the. claims.

In the accompanying drawings Figure 1 is a perspective view of thedevice; Fig. 2 is a bottom view thereof, and Fig. 3 is a longitudinalcentral section of the lower end; Fig. 4 is a plan view of a modifiedform of mouth; Figs. 5, '5, 7, are details thereof.

In these views A is the bag formed of closely woven fabrieor otherflexible material. The upper end thereof is closed and the lower end isprovided with asmall circular opening B through which the dust isprojected into the bag by the action of the machine. A strip C offlexible cloth has one of its ends attached to the bag about the openingB and has its lateral edges attached to the side of the bag throughoutthe entire Specification of Letters Patent.

length of such strip, thus forming an inlet passageway for dust ladenair whose upper end opens into the bag interior at a point above thelower end of the bag. lln the present embodiment one side of thispassageway constitutes also the side of the bag at that point. The wallof this passageway being flexible and being free at its inner end asshown at C, this arrangement provides an automatically acting closingdevice or valve element for the bag when the pressure changes itsdirection from an inwardly tending current to an outwardly tendingcurrent.

If the inner extremity of the valve or the entire length thereof shouldbe left free on all sides, a certain throbbing action of the valve whenthe machine is working as it throws itself from side to side in the bagwould make such a noise as to be disagreeable to the user.

To make the removal of the contents of the-bag easy without removing itfrom the machine, an opening H is formed upon the lower side near thelower end of the bag. This opening extends across the bag and isprovided with extended lips h, 71, which are closed with a clip Jslidingly attached or of any convenient sort when the machine is in use;but which can readily be removed to discharge the contents of the bag.

The advantages of the improvements above enumerated are obvious in thegreat convenience in use thereby provided.

Tn Figs. 4, 5, 6, and 7 a preferred form of discharge opening for thebag is shown. Here K is a semicircular metal rim for one edge of theopening which is provided with a recess 7:. lln this recess is shown awire L which is pivoted in the ends of the rim K by means of loose pivotpins M which permit the mouth to open but it will snap shutwvhenreleased, owlng to the spring action of the parts.

The rod L lies normally within the groove in the member K, and ispreferably adapted to spring back into such position when the parts arerelatively displaced by the movement of the rod L.

The edge of the bag is attached on one side to the rod L and on theother side to the member K. A. tight closure is made when the member Lenters the groove K throughout its length.

Having described the invention what I claim as new and desire to secureby Letters Patent is: r

1. In a dust bag for vacuum cleaners, an elongated inlet for the dustladen air opening into the bag at a point above its lower end, the wallof which inlet is collapsible and connected "throughout substantiallyits entire length to the bag wall.

2. In a dust bag for vacuum cleaners, an elongated inlet for the dustladen air open ing into the bag at a point above its lower end, the wallof which inlet is collapsible and supported by being attached to the bagWall.

3. A bag for collecting the discharge from a vacuum cleaner, saidbag'provided with an inlet opening 'at one end and with an outletopening adjacent thereto at the underside of said bag, a closure forsaid outlet opening, and a flexible member having one of its endssecured in said opening and having itsedges secured to one side of thebag throughout the entire length of said member so as to form anextension of said inlet within said bag.

4. A bag for collecting the discharge from a vacuum cleaner, said bagprovided with an inlet opening at one end, and with a passageway leadingfrom said inlet opening to 5. A dust bag for vacuum cleaners, comprisingthe bag proper, said hag being provided with an inlet for dust laden airand with an outlet for the removal of refuse, means for closing saidoutlet and a flexible member secured to said bag through substantiallythe entire length of said member to provide a conduit forming anextension of said inlet within said bag, said conduit opening into saidbag at a point above the bottom thereof whereby there is formed a pocketfor the collection of refuse.

In testimony whereof, I hereunto set my hand this 18th day of December1914.
